The store/mongo package implements Shield's store.Store interface using the grove ORM with the MongoDB driver. It stores all Shield subsystem data as documents with automatic index creation, making it a natural fit for deployments that already run MongoDB.

Usage01

import (
    "context"
    "log"

    "github.com/xraph/grove"
    "github.com/xraph/grove/drivers/mongodriver"
    "github.com/xraph/shield/store/mongo"
)

db, err := grove.Open(mongodriver.Open("mongodb://localhost:27017", "shield"))
if err != nil {
    log.Fatal(err)
}

s := mongo.New(db)
if err := s.Migrate(context.Background()); err != nil {
    log.Fatal(err)
}

Grove Migrations04

The store exports a Migrations group for use with Grove's migration orchestrator. This enables tracked, versioned migrations across all stores in your application:

import mongostore "github.com/xraph/shield/store/mongo"

// mongostore.Migrations is a migrate.Group for the shield mongo store.
// Register it with the grove migration orchestrator for coordinated migrations.

When to use05

  • Document-oriented workloads where MongoDB is the primary data store.

  • Horizontally-scaled environments requiring sharding.

  • Teams already running MongoDB in their infrastructure.
